I've tried it from Squeak - the result is the same. However, "/dev/stdout"
is not considered to be a "regular" file. If you do the same with a usual
file handle, only the second write should show the effect. That is at
least what Squeak is doing if I try

| f1 f2 |
(FileStream newFileNamed:'blurb.bla') close. "So it's there"
f1 := FileStream oldFileNamed:'blurb.bla'.
f2 := FileStream oldFileNamed:'blurb.bla'.
f1 nextPutAll:'First hello'.
f1 close.
f2 nextPutAll:'Second hello'.
f2 close.

And that is what should happen, because at the point of creation of the
file handles the file has zero length. BTW, I didn't try from Wintel but
it should be the same unless some weird share mode has been set which is
- now that I think of it - quite possible ;-\
